“…With the development of China's economy and the improvement of people's living standards, a high and stable yield of maize is imminent, and it is urgent to find new agricultural technologies and products [1][2][3][4]. The rise of nanomaterials in the 1980s has attracted wide attention from scientific researchers and explored the possibility of their application in various areas [2].…”

“…They are increasingly widely used in agricultural production and have outstanding prospects in improving production efficiency, such as nano-pesticide, nano-fertilizer, soil passivator, etc. Research shows that nano-materials can improve crop stress resistance and protect them from pests, improve crop photosynthesis efficiency and root nutrient absorption and water transport capacity and improve crop yield and quality, thereby reducing fertilizer application [3,4]. In the agricultural production process, compared with the traditional formula, the use of nano formula pesticides and other nano formula agricultural chemicals can improve their efficacy, which can be achieved by reducing the size of active ingredients and other compounds to the nanometer range, mixing them into nano lotion or nano dispersions, or adding them to solid lipids or polymer nanocapsules.…”

Carbon nanotubes (MWCNTs) and nano-silica (nano-SiO2) are widely used in the field of life science because of their special physical and chemical properties. In this study, the effects of different concentrations of MWCNTs (0 mg·L−1, 200 mg·L−1, 400 mg·L−1, 800 mg·L−1 and 1200 mg·L−1) and nano-SiO2 (0 mg·L−1, 150 mg·L−1, 800 mg·L−1, 1500 mg·L−1 and 2500 mg·L−1) on maize seedling growth and relative mechanisms were explored. The main results are as follows: MWCNTs and nano-SiO2 can promote the growth of maize seedlings, and promote plant height, root length, the dry and fresh weight of seedlings, root–shoot ratio and so on. The ability to accumulate dry matter increased, the relative water content of leaves increased, the electrical conductivity of leaves decreased, the stability of cell membranes improved and the water metabolism ability of maize seedlings increased. The treatment of MWCNTs with 800 mg·L−1 and nano-SiO2 with 1500 mg·L−1 had the best effect on seedling growth. MWCNTs and nano-SiO2 can promote the development of root morphology, increase root length, root surface area, average diameter, root volume and total root tip number and improve root activity, so as to improve the absorption capacity of roots to water and nutrition. After MWCNT and nano-SiO2 treatment, compared with the control, the contents of O2·− and H2O2 decreased, and the damage of reactive oxygen free radicals to cells decreased. MWCNTs and nano-SiO2 can promote the clearance of reactive oxygen species and maintain the complete structure of cells, so as to slow down plant aging. The promoting effect of MWCNTs treated with 800 mg·L−1 and nano-SiO2 treated with 1500 mg·L−1 had the best effect. After treatment with MWCNTs and nano-SiO2, the activities of key photosynthesis enzymes PEPC, Rubisco, NADP-ME, NADP-MDH and PPDK of maize seedlings increased, which promoted the opening of stomata, improved the fixation efficiency of CO2, improved the photosynthetic process of maize plants and promoted plant growth. The promoting effect was the best when the concentration of MWCNTs was 800 mg·L−1 and the concentration of nano-SiO2 was 1500 mg·L−1. MWCNTs and nano-SiO2 can increase the activities of the enzymes GS, GOGAT, GAD and GDH related to nitrogen metabolism in maize leaves and roots, and can increase the content of pyruvate, so as to promote the synthesis of carbohydrates and the utilization of nitrogen and promote plant growth.
